ADJUSTABLE LEG FOR SINKS AND THE LIKE Filed June 20 ATTORNEY.

Patented May 19, 1931 UNITED STATES WALTER J'. KOHLER, JR., OF KOHLER,WISCONSIN, ASSIGNOR TO KOHLER COMPANY, OF v PATENT? OFFICE KOHLER,WISCONSIN, A CORPORATION OF WISCONSIN ADJUSTABLE LEG FOR SINKS AND THELIKE Application filed' June 20,

This invention has for its object to provide an adjustable leg forenameled plumbing ware having deep surrounding apron flanges such assinks and particularly electric sinks, which, because of their weight,are desirably provided with legs in addition to their other support.

An object of the invention is to make the leg ofthe same material as thesink, that is enameled iron, and to provide it wlth an adjustment whichwill be located. behind the apron flange where it cannot be seen, thuspermitting the leg to present a neat and ornamental appearance withoutundue enlargement incident to telescoping sections in a visibleadjustment joint.

,Another object of the invention is to provide such an adjustable legfor sinks and the like with a spur point detachably mounted in its endto prevent the leg from slipplng.

Wit-h the above and other objects in view the invention consists in theadjustable leg for sinks and the like as herein claimed and allequivalents.

Referring to the accompanying drawings in which like characters ofreference indicate similar parts in different views,

Fig. l is a front elevation of an electric sink provided with adjustablelegs constructed in accordance with this invention;

Fig. 2 is an enlarged detail sectional view looking in the samedirection as Fig. 1 showing one of the leg members sectioned at bothends;

Fig. 3 is a sectional view on the plane of line 33 of Fig. 1;

Fig. 4; is a bottom sectional view on the plane of line 44 of Fig. 2;

Fig. 5 is a top end view of the leg member, and

Fig. 6 is a bottom end View of the leg member. I

In these drawings, 10 indicates an enameled iron sink of the type knownas an electric sink containing an electric dishwasher integral with thesink proper and provided with a deep apron flange 11 forming a roll rimaround the front and ends of the device.

Adjustable leg members 12 are provided at each of the front corners orpreferably 1927. Serial No. 200,145.

set back from the corner, as indicated in Fig. 3, and the adjustmentfeature of such legs is such that they present the same appearancewhether adjusted to their minimum length or to their maximum length,the. former being shown in Fig. 2 and the latter in Fig. 3. The legmember is hollow and its upper end is preferably reduced for appearancesake, although this is not necessary, and is provided with internalscrew threads 13, preferably in spaced relation to give the effect of anelongated bearing for a jackscrew member 14 threaded practically itsentire length and fitting in the threads 13. The upper end of the screwmember 14 is tapered and square in cross section, as shown in Fig. 5, toform a key head 15 and this fits within the tapering socket formedbetween a pair of ribs 16 cast on the bottom of the rim of the sinkintegral therewith.

At its lower end the leg member is internally screw threaded and a plug17 is threaded therein, being provided with holes 18 to receive aspanner wrench for that purpose and in its center it has a projectingspur 19 to pierce the floor surface, whether it be wood or tile, and soprevent the leg from slipping.

In order to fit the leg in place it is only necessary to insert the keyhead 15 in the socket beneath the rim of the sink and then by turningthe leg member so as to extend the jack-screw 14 while so confined inthe socket, the leg member is elongated until the spur is driven intothe floor surface and the leg attains the desired length to give propersupport to the sink.

Whatever the adjustment of the leg members they will present the sameneat and ornamental appearance for the adjustment parts-are entirelyhidden from view by the apron flange of the sink and the leg members arerigidly held in place incapable of slipping at either end by reason ofthe socket and the spur provided for that purpose.

What I claim as new and desire to secure by Letters Patent is:

1. An adjustable support for sinks and the like comprising the sink orlike member having a deep apron flange forming a roll rim,

and a leg member having a j ack-screw thread ed therein, said jack-screwengaging the under surface of the rim of the sink and thereby beingprevented from turning and the up 5 per end of the leg member beinghidden behind the apron flange in all the adjustments thereof.

2. An adjustable support for sinks and the like comprising an enamelediron sink or the like having a deep apron flange forming an enameledroll rim, and an enameled iron leg member having a jackscrew threadedtherein, said jackscrew having a tapered square end forming a key, therebeing a correspondingly tapered socket beneath the roll rim of the sinkformed between parallel ribs integral with the rim to receive the keyend of the jackscrew and prevent it from turning, the upper end of theleg member being 90 hidden behind the apron flange in all of theadjustments thereof.

8. An adjustable support for sinks and the like comprising the sink orlike member having a rim, and a leg member having a jackscrew threadedtherein, said jack-screw engaging the under surface of the rim of thesink and means to prevent said jack-screw from turning.

4;. An adjustable support for sinks and the like comprising an enamelediron sink or the like having a rim and an enameled iron leg memberhaving a jack-screw threaded therein, said jack-screw having a taperedsquare end forming a key, there being a s5 correspondingly taperedsocket in the bottom of the rim of the sink formed between parallel ribsintegral with the rim to receive the key end of the jack-screw andprevent it from turning.

5. A suitably supported sink or the like member having a roll rim withdepending apron, a socket formed in the bottom of the rim, a leg memberhaving a jack-screw threaded in its upper end with the end of the screwadapted to fit in the socket so as to be prevented from turning, saidleg member being adapted to be so engaged in the socket after the sinkis supported and then extended to engage the floor by turning it on thejack-screw, the end of the leg member and the jack-screw being concealedby the apron.

In testimony whereof, I afiix my signature.
